I may be doing something wrong, but I downloaded the VoltaicHD trial and the iVerio trial. In general I like the options I get from the quicktime export of VoltaicHD a lot more than iVerio's options, but I cannot get my video to look good when output from VoltaicHD.

I am trying to convert AVCHD files from a panasonic~SD5 camcorder and I've done it on the PC side of things just fine with an application called Procoder. However, I am more familiar with video editing on the mac side, and am looking to streamline a work-flow so I don't go insane trying to boot back and forth, and render multiple-times before I can get to work.

OK - so heres my problem:

When I load an MTS file into VoltaicHD and render it out, I get interlacing issues. Even after running the output file through other de-interlacing applications, I cannot get a file that looks 'sharp' or properly de-interlaced.

When I load that same MTS file into iVerio trial, it outputs just dandy, de-interlaced fine and @ 10,000 kbps its well enough to work with.

Again, I'd love to go with VoltaicHD, - Especially with the ability to output as dvcpro/hd from the Quicktime settings (makes FCP editing extremely smooth) but I don't know what is messing up and I have spent several days trying to figure it out. Please help! Is there anything I can do to solve this problem?

These are not my samples, but this directory has some of the SD5 clips, I have the same camera and I can reproduce the same problems with this footage.

Deinterlacing

On the Mac side, we don't offer any deinterlacing filters in VoltaicHD.

This is because iMovie and Final Cut are built to handle interlaced footage and will de-interlace the final product on export (if thats what you need). Final Cut can also export interlaced footage from your project.

A simple de-interlacing approach (probably used by iVerio, which is just ffmpeg) is to drop every second field to give a 1920x540 video, then scale it back up to 1920x1080. This results in output that looks OK, but on closer inpspection you will find that you've lost half your resolution.

So - the short answer is - try editing interlaced in FCP. Export de-interlaced by applying a de-interlace filter to the final timeline and see how this goes.
