Please post your AVI export settings. What is the source footage?

Please post a screen capture of your encoder settings.

Try to open it from the hard drive on a different computer. If the file can’t be opened on two or three computers, then burn a new copy on another drive. Was the person who helped you working on a PC or Mac? What release did they use?

In CS6 the advantage of AE is the ability to set composition settings different from the source file.
Note: Edited to review erroneous statement.

I’m not sure if it works the same way on a Mac, but in Windows you would select the mic as an input device using the Preferences > Audio Hardware > ASIO Settings.

Can you open the project from the portable hard drive? Try to narrow down whether the issue is with the file itself or the transfer to your Mac.

It depends on the export requirements and the nature of the footage. High quality SD footage can be upscaled acceptably by about 150%, which would allow you to fit a 4:3 image into a 16:9 frame. However, it might be better to leave it as 4:3 if the footage cannot be cropped elegantly.
Progressive is the better choice for streaming. Otherwise, without delivery specs you will need to test interlaced vs. progressive.

Use ProRes/DNxHD/AVC-I/Cineform for standard HD resolutions; uncompressed or PNG/JPEG2K for other sizes.
– Uncompressed formats such as RGB(A), YUV, or DPX produce the best quality but generate very large files.
– The preferred approach is lightly compressed, 10-bit, all intra-frame, 4:2:2 or 4:4:4 codecs such as ProRes, DNxHD, AVC-Intra, or Cineform. These formats withstand multiple generations of edits. However, they are only available in standard HD resolutions.
– PNG and JPEG2000 image sequences offer lossless quality and compressed file sizes. There is some risk of color conversion artifacts from 8-bpc RGB color.Another approach is to work with each sub-sequence individually within the same project, then nest them in a master timeline. (Premiere treats a sequence like a clip when it is inserted into another sequence.) This avoids the need to encode intermediate files. However, it requires all effects to be rendered during previews and final export.

To select tracks:
– With the track selector tool on, click the headers of the desired tracks, or
– With the track selector tool off, shift-click the headers of the desired tracks.

There are good general discussions in this H.264 Primer and Ben Waggoner’s book. User guides for Compressor and Adobe Media Encoder provide more product-specific information. It is also helpful to reference similar codecs such as VC-1 and MPEG-2.
