1a2bcio8 Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) You need to make sure you convert to the same frame rate otherwise this will create artifacts and distortions. You're probably filming in 25fps as 30fps is the american standard for NTSC, so try and keep it to that but refer to your camera manual to be sure.Have you tried watching the clips in premiere and then exporting them? You might find that the problems go away. I'm currently using AVCHD in Adobe Premiere Pro CS4 and mine has plenty of artifacts until I export into .wmv and then it's fine. Makes editing very difficult though and I think in my case it may be a result of my computer being too slow.That's the other thing, you could always try and get a hold of CS4 which has full (albeit potentially buggy) support for AVCHD.Also, what are you using to convert from AVCHD to another format?

You need to find out what frame rate you filmed in and match it.Is that the conversion software that canon provides with the camera?

And I just found out that your camera also supports that mode.I just looked back at what you said and the problem is due to interlacing. Is there an option to deinterlace into 25fps or 25p? Alternatively, export into 50i, interlaced and you will need to change the settings in premiere to deinterlace your clips. Deinterlacing will remove the line artifacts that you are describing. Sorry I didn't read your first post properlly, I thought you were lagging rather than experiencing interlacing artifacts.Just to note, I'm no expert on this and my knowledge is quite shaky but I still have some idea so what I'm saying may work/be true Edited January 19, 2009 by Ben Rowlands Quote Link to comment Share on other sites More sharing options...

1a2bcio8 Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) Ben has already sorted me out. Too late walford It looks like you haven't turned deinterlace on though? Also, before editing, you're probably best off converting to .avi with the least amount of compression possible. If you do deinterlace, within premiere, you will probably have to choose 1080p 25fps. I think that's the case, anyway. Edited January 19, 2009 by Ben Rowlands Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted January 19, 2009 Author Report Share Posted January 19, 2009 Right, De-Interlaced worked.Thank you Erm, Will play again again in abit. Just gotta go and take some pics of some guy. Back in an hour or so. Quote Link to comment Share on other sites More sharing options...
wally Posted January 19, 2009 Report Share Posted January 19, 2009 Can i ask why you are converting it to .avi and not editing it in AVCHD? Is that becasue you dont have CS4 with AVCHD support? Also, Ben do you have any idea what the ideal settings are for the Sony HDR-CX7 AVCHD camera, i cant find details on what fps it films at, and what format i need it in, does it want to be NTSC, i thought that was a US format?

This again means 60i (30 interlaced fps). In CS4, firstly you need to choose HDV over DV. On the next page, choose AVCHD > 1080i> AVCHD 1080i30 (60i). You'll need to select anamorphic or otherwise depending on the resolution you filmed at. Non-anamorphic means 1920*1080 and anamorphic is 1440*1080. The latter resolution is more standard and probably what your camera films at, at least as a default if it has both options.

My next question was going to be about the anamorphic bit hehe. Also another question, when i have a sequence made and try and play it in the right hand side preview screen, my computer cant seem keep up and misses out loads of frames and freezes for sections of the videos. What am i lacking in, memory? got 3gb of ram. Quote Link to comment Share on other sites More sharing options...

The only option (and a not very practical one) is to render the work area - sequence tab > render entire work area.I'm thinking about upgrading simply because of this avchd problem - I'm currently running an 'intel core 2, 2.66ghz', '2gb ram' and a '8600 GT gfx card' which is around the minimum spec. I suspect though it might relate to adobe having done a botch job with incorporating it into premiere. Perhaps there might be updates at some point to smooth it out a bit. I don't think I'm going to really be able to edit my avchd stuff if it means rendering the timeline every time i introduce a new clip. I may take the same approach as Joe and simply convert it to a better supported standard. Edited January 19, 2009 by Ben Rowlands Quote Link to comment Share on other sites More sharing options...

I do also need to see if there are any updates for CS4 as mine will always crash on the first 4 or 5 times you try to open Premeire. Quote Link to comment Share on other sites More sharing options...

It might resolve our problems. The other thing is to make sure you've got the latest drivers for your graphics card. I'm also going to give that a try.

Greetings Posted January 19, 2009 Report Share Posted January 19, 2009 Once deinterlaced, you can doulbe the frame rate to obtain the same smoothness of progressive video as in the interlaced form. Quote Link to comment Share on other sites More sharing options...

Greetings Posted January 19, 2009 Report Share Posted January 19, 2009 How do you do that? Sounds like a worthy process.If your video is 25fps (50 interlaced), just select 50fps in output, and tick deinterlace. Don't forget to increase the bitrate though since the video will have double the amount of frames. With the same bitrate, quality will be noticeably lower. As for encoding HD, the best resolution will be 720 with square pixels. No consumer or prosumer hd camera will capture more than about 700 lines despite the HDV standard having 1080 lines. So if you use a good encoding setting for 720p50 video, the quality will be pretty much the same as that of the input.Premiere CS3 supports H.264 (mpeg 4) which is supposed to be the best video encoder to date. WMV is good, but MP4 is better and on some PC's it will compress much more quickly. Also, if you're uploading anything onto Vimeo or Youtube, MP4 will be the better choice due to no audio sync issues. Quote Link to comment Share on other sites More sharing options...
