    25p mode is unique to PAL HVX0s, as 24p and 30p are unique to NTSC models.

    25p=24p approx when talking videoquality, isn't it?

    Whitebalance was set to "sun". Would another setting be better?

    Also Cine gives a lot more shutterspeeds than TV, should be a benefit? As fixed f8,0 and shutterspeed (PAL) 1/80, 1/100, 1/125 and 1/150 should give a smother change if ligth changes, if you understand what I'm trying to say......

    Vegas Histogram show a very correct colourbalance in this videoclip. We tryed shooting the same using Canon 10D, didn't get the sunset colour this good.

    so, basically, there is no way of filming 25 ftp interlaced ? Doesn't this diminish the overall quality?

    Why? Most camcorders shoot 25fps interlaced. This is the default mode for the HV.

    ou...i got fooled by the fact that when i play the raw m2t files in vlc none of those "stripes" appear, whereas when I film in the usual hdv mode they do, thus I assumed one mode captured interlaced and one deinterlaced, but thank you for clearing that up, I will properly do my homework and try not to ask questions with obvious answers.

    Isn't this what you were asking about? Interlaced shows "combing", progressive does not. So how did you get fooled?

    The catch is that progressive refresh rate is twice slower, so movement is not as fluid as with interlaced. 50p/60p will be the best of both worlds.

    well that's just it. Footage shot at 25 ftp does not show any combing at all after I capture and playback it , while the other mode , simple hdv does. Both are captured with sony vegas 8 to m2t files, but VLC and other such players open the 25 fpt one with quite the progressive look and i was wandering why. Could i have tinkered with some camera adjustments, or some settings of sony vegas?
    I only have 4 modes HDV , HDV25 ( the progressive looking one ), DV wide, DV normal and i want to shoot with the maximum quality possible.

    "Why? Most camcorders shoot 25fps interlaced. This is the default mode for the HV."

    After you said this I thought that "combing" does not show all the time even thou footage is always shot, by default, interlaced.

    I still don't get your problem. Are you asking why progressive show no combing? Because it is progressive, duh! Combing is caused by interlacing: http://www.100fps.com The HV records PF25 and PF30 progressive in the format that can be called progressive segmented frame: http://en.wikipedia.org/wiki/Progres...egmented_Frame

    Combing is shown when watching interlaced video on devices that cannot handle interlace properly, like a computer. There are players and codecs that can decode interlaced video properly, but simple players cannot do that, they show video as is. It is a good practice to deinterlace video if you want to watch it on a computer.

    well , first you said that cameras by default film interlaced at 25 pft therefore show coming right? Now you say that The HV records PF25 and PF30 progressive.
    So , in the end, the canon hv30 records Hdv25 ftp progressive and not interlaced right? This is the thing i want to know - I am watching the footage on the computer and no combing what so ever appears .

    uh, ignore that, that just some verbal glitch i picked up.(fps - frames per second) Such awful spelling. The recording mode is hdv 25pf and looks progressive on a computer, without any deinterlacing. Is that normal? -this is my question.

    PF25 is 25p which is progressive.

    PF25 is neither progressive, nor interlaced, it is PsF. Did you read the article about PsF? Ah, forget it, for practical purposes PF25 is progressive.

    Default HDV mode is 25fps interlaced, commonly designated as 25i or 50i.

    Man i think my head is going to explode trying to understand all this.

    Ok so I am shooting a short film (20 minutes) for a class so I am going to set the recording at 24p mode on my HV20. The final output will be a DVD, so it seems to be advised that you should not do pulldown if the final output is a DVD.

    So do you guys think I should still record in 24p and use it to edit when I will not be doing a pulldown? Will it still look like a "film" when the 24p is in 60i wrap or whatever?

    Since I have just a month left to shoot and edit this movie, I don't have the luxury of doing a lot of tests. That is why I am a little iffy about doing a pulldown and messing up somehow. I want the film look so I will shoot 24p, but if there is really no advantage without pulldown then I am just going to do 60i.

    Please help me guys! I been reading lot of the threads on this forum for over a week now but it is so complicated to understand what is what. When I was all set to shoot in 24p and do pulldown I came across a post that said don't do pulldown when the output is a DVD...UGHHH

    If you shoot 24p and plan only to go to DVD...then you don't have to remove pulldown. It will still have that film-like cadence.

    If you shoot 60i...it will look like video...period. If you want a film -like look from 60i...then deinterlace to 24p. But...you lose 20% of your film's vertical resolution.

    Typically....it's best to shoot 24p because it's higher resolution than 60i>24p. I think it's best to remove pulldown before you edit anything......whether you do or don't go to DVD.

    Well I am required to turn in a DVD, so my output options are limited. if it was up to me I would turn in a DVD data disc with a HD file, but I need to turn in a DVD that will play on normal DVD players.

    Considering I don't have an amazing PC and my output will be just a DVD, should I just go ahead and compress the raw files before editing? That might make my PC run smoother and I will not have to deal with huge project files.

    Hey,

    I just had a quick question about normal DV.

    This may be like a lamb to the slaughter, but I'm in the UK and so I have a PAL HV30. I'm a real newbie and I've been looking through these forums for the best way to achieve a 'movie' look to my recordings.

    However... (hold your breath) I do NOT want to use high def for the moment - I want to shoot in standard DV.

    I know that sounds stupid, but my reasoning is that I'm playing around with FCP 5 and I don't want to have to wait for hours for the footage to render.

    So, ideally I'd like to shoot in cinemode, but should I choose DV or DV-Wide from the setup?

    Thanks in advance for your help,

    machts

    Firstly, you make sure you download the new firmware which fixes the SD bug on PAL HV30s.

    Secondly, if you ever want to use the footage later, you shoot HDV and set the output to downconvert to DV.

    Thirdly, you read the manual from cover to cover!

    DV or DV wide? Well, do you want 4x3 or 16x9?

    Cheers,
    David.

    This might be the wrong topic to post in with this question but I am unsure which one to post in...so here it goes.

    I shot around 40 minutes of footage in 25P mode in HV20 and my final output is a standard Def DVD meant to play in most DVD players.

    Based on the advice I got from other users I did NOT do the pulldown and just edited in 60i timeline. Now I am confused on how to output and if I will get 16:9 widescreen or not.

    What is the best option for outputting to a DVD? (I want to use a diffrent program to create DVD menus to go along with the video)

    Also is there anything I need to do to keep my "film look" and create 16:9 widescreen image?

    Thanks a lot guys!

    25fps? If you have a PAL model you donīt need to do the pulldown and should edit in a 25p timeline. *scratches head*
    The fps donīt have anything to do with having widescreen or fullscreen. To get a proper widescreen DVD your image is squeezed to 720x480 or 576 (NTSC/PAL), a flag in the video stream tells the player to decode it as 16:9.
