Gonna need a lot more info than that to help you out.
Can you tell us EXACTLY what format (wrapper and codec) your footage is in, where it came from, what timeline info you're using, what your computer specs are, and what you're trying to encode out to?
"Can you tell us EXACTLY what format (wrapper and codec) your footage is in, where it came from, what timeline info you're using, what your computer specs are, and what you're trying to encode out to?"
Oh sure, sorry.
As I said the footage is mixed. We have Canon 7D footage (h.264) and HDV footage (Canon HV30 and Sony FX1, which are using the same codec: Apple Intermediate Codec, Linear PCM).
The audio is mixed as well: a lot comes from the HDV camcorders but I also recordered some external audio with a Zoom H4N (44100 Hz)
I don't know what you mean by timeline info but we set our sequence presets to dslr 1080p25. Normally I would export the project in hdtv 1080p 25, h.264 codec and square pixels, but I am not quite sure if this is the best. To me the HDV footage doesn't look so good in the final film. But this is another thing..
Please ask for more specific infos if needed. And thanks so far!
I use both HDV footage and audio from Zoom recorders like you are using. If it were me I would check the following first...
- Verify the areas using Zoom audio sync'd prior to rendering. The clocks in those Zooms aren't the same as the cameras so they will tend to drift.
- Verify no drop-out occured while capturing HDV footage. Drop-out can send the audio/video out of sync.
An HDV 30i sequence may be better, but you are using blended formats so that may not be an issue.
Best of luck,
Ok, that's the info we need... thanks
On a side note, your HDV footage will probably look rather poor next to your 7D footage because the color space is smaller (4:2:0 instead of 4:2:2) and because the overall quality of the image is lacking. But, I digress...
Ok, I'm not certain this is the cause, but you mention that your Zoom recordings are at 44.1k... Video timelines work with 48k audio, and I know from audio production that you will get slight timing issues trying to mix 44.1k and 48k together. Try transcoding your 44.1k audio to 48k and then line things up and export and see what happens...
Thanks guys! I'll remember your tipps.
As this project is concerned audio and video are perfectly synchronal in PP. Only after exporting it is slightly different. Do you have any suggestions what would be the best export settings in my case? I also tried to render with 44.1 k without success. :/
