Here, 친구가 marks friend as the doer of 편집한 (edited).

The phrase 친구가 편집한 영상 means the video that my friend edited.

• 친구가 = my friend is the one who edited it
• 영상은 = as for the video...

So the sentence has two layers:

1. 친구가 편집한 modifies 영상
2. 영상은 짧지만 다시 볼 만해 says something about that video

If you changed it to 친구는, the nuance would shift toward as for my friend..., which is not the most natural choice here.

편집한 is the noun-modifying form of 편집하다 (to edit).

So:

• 편집하다 = to edit
• 편집한 = edited / that edited

In Korean, verbs can directly modify nouns. So:

• 친구가 편집한 영상 = the video that my friend edited

This is very common in Korean. English often uses that/who/which, but Korean usually just puts the verb before the noun.

It is a relative-clause-like structure.

Breakdown:

• 친구가 = my friend + subject marker
• 편집한 = edited
• 영상 = video

Literally, Korean says something like:

• my friend edited video

Natural English:

• the video that my friend edited

Korean does not need a separate word like that here. The clause comes directly before the noun it modifies.

은 is the topic marker.

So 영상은 means something like:

• as for the video, ...
• the video, ...

In this sentence, the speaker is making a comment about the video:

• it is short
• but it is worth watching again

So 영상은 sets the video as the topic of the sentence.

It can also add a slight contrastive feeling, especially with -지만 (but):

• The video, though short, is worth watching again.

짧지만 comes from:

• 짧다 = to be short
• -지만 = but / although

So:

• 짧지만 = it’s short, but... / although it’s short...

In the full sentence:

• 영상은 짧지만 다시 볼 만해
• The video is short, but it’s worth watching again.

This connector is very common for linking two contrasting ideas.

다시 볼 만해 means it’s worth watching again.

Breakdown:

• 다시 = again
• 볼 = future/adnominal form of 보다 (to watch / see)
• 만하다 = to be worth doing / to be reasonable enough to do
• 만해 = casual spoken form of 만하다

So 볼 만하다 is a set expression meaning:

• worth watching
• watchable
• good enough to watch

And 다시 볼 만하다 means:

• worth watching again

No. It is different from simple ability.

• 볼 수 있다 = can watch
• 볼 만하다 = worth watching / good enough to watch

So 다시 볼 만해 does not mean I can watch it again.
It means it is good enough that watching it again would be worthwhile.

That nuance is important.

Because -ㄹ/을 만하다 attaches to the verb stem in this specific form.

For 보다:

• stem: 보-
• adnominal form before 만하다: 볼
• 볼 만하다 = worth seeing / worth watching

This is just the standard grammar pattern:

• 읽을 만하다 = worth reading
• 먹을 만하다 = decent enough to eat
• 가 볼 만하다 = worth going to see / worth visiting

So 볼 만하다 is the correct form.

Because 만하다 is treated as a separate word in this expression.

So it is normally written as:

• 볼 만하다
• 먹을 만하다
• 읽을 만하다

In casual speech, 만하다 becomes 만해, but the spacing stays:

• 볼 만해

This is standard spelling.

만해 is casual, non-polite speech.

It would typically be used:

• with friends
• with people younger than you
• in informal conversation
• in diary-style or casual written language

More polite versions would be:

• 친구가 편집한 영상은 짧지만 다시 볼 만해요.
• 친구가 편집한 영상은 짧지만 다시 볼 만합니다.

So the original sentence sounds friendly and informal.

Yes, in the sense that the editing is completed before the video is being described.

편집한 영상 means:

• the video that was edited
• the video my friend edited

This past modifier form often indicates a completed action before the noun.

But it does not always need a strong past-time-story feeling in English. It is simply the normal way to say that the editing has already been done.

Yes, a little.

• 영상 is a very common Korean word for video / footage / visual content
• 비디오 is a loanword from English and can also mean video

In modern Korean, 영상 often sounds more natural in many contexts, especially for online clips, edited content, recordings, and media.

So 친구가 편집한 영상 sounds very natural for the video my friend edited.

Yes, definitely.

That contrast is part of the feeling of 짧지만:

• It’s short, but...
• Even though it’s short, ...

So the sentence suggests:

• the video is not long
• but it still has enough value to watch again

That gives the sentence a positive evaluative tone.

Yes, rewatchable is a very good natural English gloss for it.

Depending on context, it could be translated as:

• It’s worth watching again
• It’s rewatchable
• It’s good enough to watch again

The exact best translation depends on tone, but all of these capture the main idea well.
