February 25, 2013 at 1:49 am in reply to: AVC/MP4 optimum bit rate value to rendering interviews…Thanks everybody for answering! The MainConcept Internet 720p preset seems to be the way to go indeed. And by testing variations of 1,000,000 I think I will achieve best file size x quality.
Anyway, considering this preset and my original footage characteristics, there are a couple of points I am a little bit confused:
a) In this preset the average (bps) is 8Mbps and maximum is set to 16Mbps. But since my original footage is 11Mbps, it seems I could set the maximum bit rate to 11Mbps to avoid a supposed overkill of the preset working unnecessarily at 16Mbps. Does it make sense?
b) My original footage is 1280×720, 60p, 11Mbps.
When rendering, I am maintaining same resolution (1280×720), but downsizing the fps to 30p. Let’s suppose I use CBR to try achieving an optimum quality as close as possible to my original footage. Since the fps are half of the original footage, it seems logical that I could downsize the bit rate to 5.5Mbps without quality loss. In other words, using the same 11Mbps would be overkill since I am using half of the fps when rendering. Does it make sense?Cheers,

February 24, 2013 at 8:26 pm in reply to: Sony or MainConcept AVC/MP4 are rendering levels incorrectlyThanks everybody for answering!
Some points:
“What quality settings are you using when you render?
What happens if you render an untouched version of the same video using the Sony or MainConcept templates?”=> About quality settings, I am using the template “internet 720p” (MainConcept).
=> If I render an untouched version the output is correct. The problem happens when I use the “levels” adjustment. I realized that to the MainConcept and Sony AVC codecs the preview is inaccurate, following somehow what is described in the article indicated by Bob. But what is really strange is that to XVid/AVI the preview is accurate, being the rendered file what should be expected.
=> So far, the only conclusion I can achieve is that the preview is inaccurate to MainConcept and Sony AVC, being the “blacks” increased more than expected when using these codecs.

Thanks for answering James.
Besides what you pointed out, I should say other problem I found is that the DSLR are limited to a short time of recording, around 30 minutes. Considering my main usage is to record interviews that takes around 2 hours, the only way to go seems to be through a camcorder indeed.

About to “drop the AEProject directly in Vegas”, are you referring to new Vegas 12 feature? Would it be expected that all kind of projects created in AE be loaded in Vegas 12?

The issue is with “Toggle Animate/Static Mode” indeed.

August 28, 2012 at 11:17 pm in reply to: Clone tool or other better one to remove lapel mic wire (RED5)Hi Peter,
After your tip I found my way is with “Wire Remover” tool. Many thanks!
However, I was not able to achieve a good result by using the motion tracker. The interviewee many times pass the hand over the mic wire and it seems I will need to adjust keyframe manually.
On this subject(adjust keyframe manually) I would appreciate other tip from you. Something strange is happening: I set the first keyframe; then I set the second one. The changes I made in the second makes the first change as well. I mean, if I have 10 keyframes and I change one of them, all the others will change to the same.
I think it should be a property/setting issue. I had worked with keyframes on BBC lighting properly, but now even this filter is showing same strange keyframe behaviour I am facing with “wire remover”.
Any idea what to do?
Cheers,

Thanks everybody for help on this thread!
I found a useful guide on audio restoration through Izotope RX:
