I'm a guy that doesn't have any qualms shooting images with a crop more than s35, so the G7 looks like it'll be a great cheap cam to get regardless if I ever put a speedbooster on it. Good to hear about some of the details with the adapter, however. Always nice to know what the options are.
I don't mind crops, I mind the lack of options for wide vintage glass.

I'm drooling all over these lenses. The 55mm is a T/1.1 and these lenses can adapted to EF and look remarkable and cinematic. Even though the guy on Nofilmschool said they are impracticable, I think quite the opposite.
Yeah they look great, are you going to make an offer?
-
Those Kerns are excellent. They may be the ultimate lenses for the bolex or bmpcc.

This is the one I was looking at for background actors. In the shot I will be following and/or they will be pushing the cam, on a steady cam, through a party. The conversation the main two actors wil be having will be commentated by the other background actor's, but in a comical way... Meaning they may say something about liking a guy and as they pass a group of people, a background actor, having a totally different conversation will be heard saying, "not a chance." I don't have access to a boom operator skilled enough to follow the flow and move the mic back and forth, so I want to do the old recorder in pocket and lav trick. I could need anywhere between 6 to 10 actors for these background characters... That's a lot of money for quality recorders, so I was hoping something like this might work and not sound too horrible...

to put it in camera terms, bit rate is like dynamic range and sample rate (kHz) is like frame rate. 24bit has a range of 144db while 16bit has a range of 96db. the latter is more limiting in terms of how from you can swing between your lowest lows and highest highs. But just like how cameras also have a "useable" dynamic range, the noise floor in an audio recording device is also a limiting factor. either way, 24bit gives you more room to work with.
a sample rate of 48khz is adequate for dialogue, but if you were to be recording sound effects that you might want to slow down in post and manipulate to create new sounds, you'd want to record them at a higher sample rate (higher resolution) to capture more detail in the audio. in camera terms, it's like if you wanted a slow motion shot. if you shot at 24fps and slowed it down to half speed in post, you'd be doubling frames. but if you captured it at 48fps and slowed it by half, it would still be smooth in a 24fps sequence.
Okay, that makes sense. So, is there any truth to what I read that 96 kHz can actually cause distorted sounds? If recording 96 kHz, do I still want to keep my dialogue peaking at -12, or does that change?
Next question, I am using an older model Olympus field recorder. I just finished editing a short and I was pleased with the sound quality. I recorded it at 96/24. After reading that sometimes recording too high can be detrimental, I looked at my recorder and found my options to be
1. 96/24
2. 88.2/24
3. 48/16
4. 44.1/16
5. 44.1/mono
Since I do not have a 48/24 option, should I just stick with the 96/24?
Also, I wrote in a previous comment that I have an upcoming shoot that requires a lot of movement and a lot of audio. I was going to set up my main two actors with the Olympus recorders I have, but I also was thinking of getting inexpensive voice recorders for the background players. To keep the cost down, I have found an inexpensive recorder that records wav files but the specs are only slightly higher than the highest MP3 recording settings. I think it's 24/396. Will this audio be usable because it is a wav file or is it basically like using an uncompressed equivalent to MP3 quality?
Again sorry about all the questions and I really appreciate any info.

Sorry for all the questions, I get that 24 bit 48khz is ideal. But I have an upcoming shoot that takes place at a dinner party. The camera is going to float through the room with my two main characters, but I want to hear snippets of background conversation. It's important to the scene. My plan is to have as many as a dozen audio recorders in the actor's pockets. There are some inexpensive voice recorders that record wav files with the bitrate numbers slightly higher than what an MP3 would record at it's highest settings.
-
Don't record in MP3 format for any broadcastable material - MP3 quality audio present in a mix can fail QC (in TV land) - 24 bit 48k is used in 99.99% of every film (AAA titles) and TV mix I've done - music, sometimes at 96k if you're feeling extravagant!
Okay, what does the 24 bit number pertain to? And also the 48khz number. What about a lower wav recording... 16bit 44.1 or even lower wav recording? Is the bit number similar to the dynamic range number in video?
-
From my understanding, you do want to have tiers to promote, upsell, some donations.
-
Yeah but the special edition movie soundtrack version with cover art is a new ballgame.
-
I'd make it 20 or 25 bucks though. Watch pbs during their telethons, the point is why should I donate 10 bucks when for 10 bucks more I get this great tote bag. Apple is the king of that as well for their upgrades.
-
The next question then becomes... Are you gaining anything by recording in wav, when it will be compressed later for delivery anyway? Why not just record at a high bitrate MP3?
-
For spoken dialog, 16bit 44.1kHz MP3/AAC 128kbps or higher is plenty good. Here's how you can prove it to yourself: record a test at 96kHz 24bits WAV. Convert this recording to 128kbps 44.1 MP3 or AAC. Do all post work on the recordings, then export for delivery- H264 will use AAC. Can you hear any difference?
Everything we hear now is AAC or MP3, except for the movie theater and BluRay. Far more important than WAV vs. AAC/MP3 is the quality of the preamps (Sound Devices is my favorite- best bang for buck), mic, mic placement, recording level, and ambient noise level. For music and Foley fx, higher rates and uncompressed can be helpful, though the final mix will be compressed in most cases for delivery.
If everyone listened using Stax headphones and B & W speakers, things might be different ;)
Ok thanks, I am a little ignorant when it comes to audio... What does the kHz and the bit number represent... Or measure?
-
A free soundtrack?
-
24bit 48k please
So, you think that is more than enough for low budget, indie movie dialogue?
-
Yeah, I would definitely do wav recordings but is 96 overkill? I read that depending upon the audience's listening equipment, anything over 48 could actually make your audio sound worse... Of course this article was geared towards music, which I assume would be more demanding due to the higher frequencies. But there is something interesting about having a half dozen small voice recorders dispersed across a set, at actor's marks, plus the ones in the actor's pockets. But I'll just probably stick to what I have... It's working so far.
-
so, i have been messing around with audio recording options. thus far, i have been using an olympus field recorder at 24bit/96khz and have been getting good sound with a lav.
A friend of mine recently tested audio with an olympus voice recorder, recording at high bitrate MP3 with a neewer lav and the quality is amazing.
I wouldn't say it's any better than my wav recordings but it sounds just as good.
So, my question is... are 24/96 recordings overkill?
A lot of inexpensive voice recorders record 24/48 or 16/44.1, is this level good enough? I even noticed that mpeg streamclip's highest, audio transcoding setting is 48khz, should i be taking the hint?
my higher end olympus field recorder's still fetch a good price on the used market, if a lower bit and sample rate is good enough, i could have 5 lav setups instead of two.
Thoughts?

Or... Two possible donors are awoken, in the middle of the night. They both hang up the phone and look at their beautiful wives lying in bed, one chooses sleep, the other chooses donation. He gets up, gets dressed and goes outside into the night chill. There are no taxi's in sight, he runs. Use the heartbeat and ticking clock idea, until your donor arrives and donates. The girl lives, he goes home. His wife awaits him with a smile. They go back to bed. Time lapse the rising sun in the window, pull back and see we are now with the the guy who chose sleep. His wife isn't in bed with him anymore. He gets up, goes outside to get the paper... He gets hit by a truck. The only possible donor, already gave blood, he bleeds out and dies at the hospital.
-
Or... Streamline your idea and keep it simpler. When your hero weighs his options, he chooses sleep. We then learn about dahlia and her family, without the blood donation... She dies. At that point your hero awakens from a dream, looks at the clock and sees that only 5 minutes has passed. He gets up, gets dressed and runs to the hospital. His heart pounds. Cut to the hospital, the clock ticks, but it clicks backwards... As if it is ticking down. Finally he arrives at the hospital and donates the blood. Dahlia lives. The end.
-
Remember, you're idea is technically a beat the clock thriller.
-
I would crosscut between the two phone calls, the two options, you never know who is connected to who and then proceed with the climax of who was saved. Use the beating of his heart, when he's running to coincide with the ticking of a clock in the hospital. In fact, I probably wouldn't show Sarah until the end. Make the audience feel for and root for dalia. And then do the reveal that her donor never showed. Show Sarah, happy and healthy as dalia lies there dead, covered by a sheet.

Found a couple of really cheap Bolex H16 cameras with lenses in the turrents.
Bought one to use the lenses with the Digital Bolex and BMPCC but will also shoot some 16mm film with it.Did a quick test when I got it home today.
I have a set in d mount that I use with my Pentax q7... Great lenses.

Quick review of my Zeiss Tevidons.
Not as cheap as my cheapest Zeiss Glass but still affordable compared to modern glass.Nice!!! They seem like the perfect combo for either the D16 or the BMPCC. I loved the shots with the 10mm and the flowers... The flares were awesome.
-
Very nice. The BMPCC footage looks excellent. And the RX100ii holds up pretty damn well. Congrats!!!
