MTS vs M2TS & Left+Right Pan vs 4audio channels…
I have a big project (50 minute short film) that I am editing. It was shot with 2 Canon Vixia’s and a Zoom4Hn recorder for sound. Now I need to synch my good Zoom audio with my Vixia footage and am having some trouble with the re-rendering to attach the new audio. I have the clips all paired up on the timeline using the audio spikes made with my shot slate and have “regioned” each clip to Batch render them.
First Question: What I still have not figured out how to get the render settings template to NOT re-render the video. I start with footage from the Vixia camera, an .MTS file that is 38MB, what I end up with after the MUXing is a .M2TS that is 100MB which triples my file size. While this is not an issue for 1 clip, multiply that by 800 clips and I will be having a problem. I am using Sony Vegas 10c and it does not seem to have any “match” feature to have the video just pass through untouched with the new audio the only thing being rendered. How can I best approach this issue? Is the additional file size coming from the new audio? Do I just have to suck it up and make additional storage available?
Second Question: Sometimes my Vixia Audio is better than my Zoom Audio so I am wanting to keep both attached so that I can mix later them as I see fit to add background tone or to completely dial it down because of wind noise or whatever. It was suggested to me to Pan each track to the opposite position and that this would give me some sort of control later on that. I was hunting for maybe a way to get 2 stereo pairs and control the levels that way. How can I best approach this issue?

ken,
1)
only few professional formats allow you to export video without recompression and canon vixia falls outside of the group. it gives you – i suppose avchd? it is not pro standard for the input and your frames will be recompressed. as an input you would need….
hit help in vegas and type ‘rendering projects’ – you will have your answer for that.2)
don’t ever listen to that person in the future.
i assume that now for any video you have one stereo audio from zoom and one stereo audio from vixia. if you pan them and mix in the final file you end up with two mono sound streams.
if you can’t decide now which audio to choose, make a temporal choice and render your files this way. in the next step render only alternate audio takes with the same names your just rendered videos have. this way you can easily match them together in the future. you probably have them stacked above or below the video so you have your regions marked. just make sure all your alternates are on a single track, make that track solo and render your regions to wavs. it will be just another batch rendering pass for the alternate audio.hope that helps and maybe some other fellow has any better workflow to do that – i will be pleased to learn sth new:)
regards

Yes this does help and your observations pan out. Since posting I have been experimenting with outputs and my stereo pair from Zoom and Vixia do indeed get mixed and I then cannot make a choice between the good audio and the Vixia Audio. Oh and yes the formats are AVCHD. I was beginning to suspect what you suggest as my solution, to make the temporal choice now and render. I’ll keep the file names the same so later I can “swap” folders so alternate audio can be later rendered as needed.
