    I’m using Panasonic TM700 for video shooting with 1920x1080 setting. I’m window user before this, all my video editing done with Window PC with application like PowerDirector8, Adobe premier pro element8. Yes, Window processing is like turtle. Very slow. Thus, I’m switching to new iMac 21’5 i5 with iMovie 11.

    I am very disappointed to see the video generated out from iMovie have degraded the image quality, a lot of noise especially on shadow area. The mov generated by iMovie is export as 1080 resolution.

    I root caused the problem, it seems like when iMovie imported the ‘mts’ file direct from Panasonic TM700, the video image has already degraded. Thus the output will have the same quality as well.

    It is definitely not Panasonic TM700 problem, as the same video produced on window PowerDirector is in HD quality. As clear & sharp as the original mts file, no noise, no distortion.

    Anyone can advise? How to get iMovie to produce the same quality as the raw file from camera?

    Many thanks!

    LOL......dude didnt you read all the other post Mac suck at Hd video editing especially M2ts good luck you would have to spend another $1500 in software if you want your output video to match the quality of the input....

    PS ....watch the apple fanbots howl and snare and threaten.... but in the end after coming from windows and seeing how easy it was you would understand what I mean

    Perfect quality in iMovie with Panasonic TM700 - TM900


    I have the similar camcorder, and the exported movie is in very googd quality.

    First - how do you make the import? You should in Preferences set up "Import HD video" as "Full - original size". Then if you are in Import window (you see clips with movies from your camera) set off all analyzis. You shouldn't make any optimalisation or any analyzis. Your original clips are AVCHD in .mts or .m2ts formats but during the import iMovie uses AIC codec (Apple Intermediate Codec), which is little loosy, but it absolutly doesn't destroy the quality!

    You should export the movie using Share / Export using QuickTime. Then set up the options: codec H264 (or ProRes if you got it), size: 1980 x 1080.

    On my 55'' TV the results is very good!

    Try Adobe Premeire Elements ($70) it's reasonably priced and does a good job at basic video editing. There is very little loss in picture quality and no transcoding or conversion of M2ts, files are gets imported instantly.

    Shot with one of your(aka my Canon T2i so don't even dis the camera) cameras using iMovie 9. Certainly not "pro" but horrible either. I suggest exporting using quicktime (its an option under iMovie under "Share") is takes like 10x longer but you can essentially export uncompressed video/audio. Also I can not stand using windows for anything graphically...it just seriously blows I haven't a clue why but no matter how much RAM a PC has it always gets bogged down by large files. Just my anecdotal experience though. Carry on.
