Crossfades are jittery and shakey

Hi
I have a problem with the crossfades using msp 8 . Im getting jittery/shakey crossfades

I upgraded MSP 8 with the latest Service Pack 1

Tried it three different firewire cards and also on two other PCs and all do the same.

I overlap the two video streams and then do an instant preview and all looks well on the pc screen.
As soon as I do a full preview to my main TV monitor i get this problem.

I have even rendered it first then played it back to my TV monitor and it is still the same.

I am sending it out by firewire DV Type 1. Lower Field first

I have tried all the settings from lower field, upper field, de-interlace, frame based, flicker reduction and nothing seems to make it any better.

The only time i can get it to work is if I render it with no compression and then re-render again in DV Type 1 but this takes up alot of harddrive space.

Any suggestions how to stop this problem would be much appreciated.
Cheers Andy

Hi
I have a problem with the motion paths using msp 8 .

The moving path i used was 2D Advanced.
I angle the picture from the top left and then it moves until I get the angle I require to the top right using the distortion box.

When I either come to preview or render the moving path it is not playing back smoothly

I have upgraded msp 8 with Service Pack 1 and it is still the same.

I am sending it out by firewire DV Type 1. Lower Field first

I have merged your two posts into one, as the subject is essentially the same, and I locked the other one to avoid duplication.

You don't give us any details of how you are viewing your projects, but allow me to make a guess: you are judging the quality with the Preview Window and you have it set on Instant Play. Set it to High Quality and it will render before the preview, which will be smooth.

Keep everything on Lower Frame First.

Hi Devil

That is correct

When on instant preview it is being viewed on the pc screen and when on high quality it is viewed down the firewire link to a canon xl1 and xl1h TO a jvc Hi res studio monitor

With regards to the moving path it shows up the same on instant preview and high quality and render.

The crossfade is ok on the pc monitor but not on high quality output to the studio monitor even when rendered.

When the rendered footage is played back on the pc monitor it is okay but when sent by firewire it has this problem

All footage has been captured as DV type 1 and edited using lower field first.

I have tried different firewire cards but again the result is the same.

Any Ideas??

cheers andy

Yes DV is not meant for viewing on a computer but on a TV. A computer does not have interlacing, DV does. If you want to have it for computer viewing, you will have to convert it to another format which allows progressive formatting. If you were to make a DVD from it, I feel there will be no problem.

Hi Devil

I know dv is not used for viewing on a PC

I want the footage to be recorded back to DV tape after all my editing is done.

I need the crossfade to be smooth and the moving path also to be smooth when recorded back to DV tape but this is not happening.

Everything else is working okay on playback to dv tape except this irritating problem.

Very frustrating.

Please help

Cheers Andy

Hi Everyone.

Just sorted out my problem and now works a treat...

Maybe I should become a moderator?

why don't you share your answer with us all? Or was it one of those "is it plugged in at the wall?" type moments?

I worked out how to change the brake discs and pads on my car, so I asked Ford if maybe I should become a manager at one of their service centres.

Not really, but hopefully you realise how daft your suggestion sounds. Product knowledge isn't at all important for a moderator, it just helps. Tact, diplomacy and common sense are far more useful...

Tact? Diplomacy? Me? You must be joking!

Greetings,

Has Andy ever posted the solution? I have the *exact* same problem. I have been taking the problematic segments and doing a 'create video' uncompressed. Then doing a 'convert video' to AVI with DV compression. Then re-placing the problem sections.

I have not had luck with copy-paste fixing the issue.

Regards,
Steve
